Archeology and Historic Preservation; Secretary of the Interior's Standards and Guidelines

AGENCY: National Park Service, Interior. ACTION: Notice.

SUMMARY: This notice sets forth the Secretary of the Interior's Standards and Guidelines for Archeology and Historic Preservation. These standards and guidelines are not regulatory and do not set or interpret agency policy. They are intended to provide technical advice about archeological and historic preservation activities and methods. DATE: These Standards and Guidelines are effective on September 29, 1983. FOR FURTHER INFORMATION CONTACT: Lawrence E. Aten, Chief, Interagency Resources Division, National Park Service, United States Department of the Interior, Washington, D.C. 20240 (202-343-9500). A Directory of Technical Information listing other sources of supporting information is available from the National Park Service. SUPPLEMENTARY INFORMATION: The Standards and Guidelines are prepared under the authority of Sections 101(f), (g), and (h), and Section 110 of the National Historic Preservation Act of 1966, as amended. State Historic Preservation Officers; Federal Preservation Officers including those of the Department of Agriculture, Department of Defense, Smithsonian Institution and General Services Administration; the Advisory Council on Historic Preservation; the National Trust for Historic Preservation; and other interested parties were consulted during the development of the Standards and Guidelines; additional consultation with these agencies will occur as the Standards and Guidelines are tested during their first year of use.

Purpose

The proposed Standards and the philosophy on which they are based result from nearly twenty years of intensive preservation activities at the Federal, Statei and local levels.

The purposes of the Standards are: To organize the information gathered

about preservation activities. To describe results to be achieved by

Federal agencies, States, and others when planning for the identification, evaluation, registration and treatment of historic properties.

To integrate the diverse efforts of many entities performing historic

preservation into a systematic effort to preserve our nation's cultural heritage.

Uses of the Standards

The following groups or individuals are encouraged to use these Standards:

Federal agency personnel responsible for cultural resource management pursuant to Section 110 of the National Historic Preservation Act, as amended, in areas under Federal jurisdiction. A separate series of guidelines advising Federal agencies on their specific historic preservation activities under Section 110 is in preparation.

State Historic Preservation Offices responsible under the National Historic Preservation Act, as amended, for making decisions about the preservation of historic properties in their States in accordance with appropriate regulations and the Historic Preservation Fund Grants Management Manual. The State Historic Preservation Offices serve as the focal point for preservation planning and act as a central state-wide repository of collected information.

Local governments wishing to establish a comprehensive approach to the identification, evaluation, registration and treatment of historic properties within their jurisdictions.

Other individuals and organizations needing basic technical standards and guidelines for historic preservation activities.

Organization

This material is organized in three sections: Standards; Guidelines; and recommended technical sources, cited at the end of each set of guidelines. Users of this document are expected to consult the recommended technical sources to obtain guidance in specific cases.

Review of the Standards and Guidelines

The Secretary of the Interior's Standards for Rehabilitation have recently undergone extensive review and their guidelines made current after 5 years of field use. Users and other interested parties are encouraged to submit written comments on the utility of these Standards and Guidelines except for the Rehabilitation Standards mentioned above. This edition will be thoroughly reviewed by the National Park Service (including consultation with Federal and State agencies), after the end of its first full year of use and any necessary modifications will be made. Subsequent reviews are anticipated as needed. Comments should be sent to Chief, Interagency Resources Division, National Park Service, United States Department of the Interior, Washington, D.C. 20240.

Secretary of the Interior's Standards for Preservation Planning

.Preservation planning is a process that organizes preservation activities (identification, evaluation, registration and treatment of historic properties)'in a logical sequence. The Standards for Planning discuss the relationship among these activities while the remaining activity standards consider how each activity should be carried out. The Professional Qualifications Standards discuss the education and experience required to carry out various activities.

The Standards for Planning outline a process that determines when an area should be examined for historic proptrties, whether an identified property is significant, and how a significant property should be treated.

Preservation planning is based on the following principles:

-Important historic properties cannot be replaced if they are destroyed. Preservation planning provides for conservative use of these properties, preserving them in place and avoiding harm when possible and altering or destroying properties only when necessary.

-If planning for the preservation of historic properties is to have positive effects, it must begin before the identification of all significant properties has been completed. To make responsible decisions about historic properties, existing information must be used to the maximum extent and new information must be acquired as needed.

-Preservation planning includes public participation. The planning process should provide a forum for open discussion of preservation issues. Public involvement is most meaningful when it is used to assist in defining values of properties and preservation planning issues, rather than when it is limited to review of decisions already made. Early

Federal Register / Vol. 48, No. 190 / Thursday, September 29, 1983 / Notices 44717

and continuing public participation is essential to the broad acceptance of preservation planning decisions.

Preservation planning can occur at several levels or scales: in a project area; in a community; in a State as a whole; or in the scattered or contiguous landholdings of a Federal agency. Depending on the scale, the planning process will involve different segments of the public and professional communities and the resulting plans will vary in detail.-For example, a State preservation plan will likely have more general recommendations than a plan for a project area or a community. The planning process described in these Standards is flexible enough to be used at all levels while providing a common structure which promotes coordination and minimizes duplication of effort. The Guidelines for Preservation Planning contain additional information about how to integrate various levels of planning.

Standard L Preservation Planning Establishes Historic Contexts

Decisions about the identification, evaluation, registration and treatment of historic properties are most reliably made when the relationship of individual properties to other similar properties is understood. Information about historic properties representing-aspects of history, architecture, archeology, engineering and culture must be collected and organized to define these relationships. This organizational framework is called a "historic context." The historic context organizes information based on a cultural theme and its geographical and chronological limits. Contexts describe the significant broad patterns of development in an area that may be represented by historic properties. The development of historic contexts is the foundation for decisions about identification, evaluation, registration and treatment of historic,properties.

Standard II. Preservation Planning Uses Historic Contexts To Develop Goals and Priorities for the Identification, Evaluation, Registration and-Treatment of Historic Properties

A series of preservation goals is systematically developed for each historic context to ensure that the range of properties representing the important aspects of each historic context is. identified, evaluated and treated. Then priorities are set for all goals identified for each historic context. The goals with assigned priorities established for each historic context are integrated to produce a comprehensive and consistent set of goals and priorities for all historic

contexts in the geographical area of a planning effort.

The goals for each historic context may change as new information becomes available. The overall set of goals and priorities are then altered in, response to the changes in the goals and priorities for the individual historic contexts.

Activities undertaken to meet the goals must be designed to deliver a usable product within a reasonable period of time. The scope of the activity must be defined so the work can be completed with available budgeted program resources.

Standard III. The Results of Preservation Planning Are Made Available for Integration Into Broader Planning Processes

Preservation of historic properties is one element of larger planning processes. Planning results, including goals and priorities, information about historic properties, and any planning documents, must be transmitted in a usable form to those responsible for other planning activities. Federally mandated historic preservation planning is most successfully integrated into project management planning at an early stage. Elsewhere, this integration is achieved by making the'results of preservation planning available'to other governmental planning bodies and to private interests whose activities affect historic properties.

Secretary of the Interior's Gtidelines for Preservation Planning

Introduction

These Guidelines link the Standards for Preservation Planning with more specific guidance and technical information. They describe one approach to meeting the Standards for Preservation Planning. Agencies, organizations or individuals proposing to approach planning differently may wish to review their approaches with the National Park Service..

The Guidelines are organized as-follows: _ Managing the Planning Process Developing Historic Contexts Developing Goals for a Historic Context Integrating Individual Historic Contexts-

Creating the Preservation Plan Coordinating with Management Frameworks Recommended Sources of Technical

Information

Managing the Planning Process

The preservation planning process must include an explicit approach to implementation, a provision for review and revision of all elements, and a mechanism for resolving conflicts within

the overall set of preservation goals and between this set of goals and other land use planning goals. It is recommended that the process and its products be described in public -documents.

Implementing the Process

The planning process is a continuous cycle. To establish and maintain such a process, however, the process mustbe divided into manageable segments that can be performed within a defined period, such as a fiscal year or budget cycle. One means of achieving this is to define a period of time during which all the preliminary steps in the planning process will be completed. These preliminary steps would include setting a schedule for subsequent activities.

Review and Revision

Planning is a dynainic process. It is expected that the content of the historic contexts described in Standard I and the goals and priorities described in Standard II will be altered based on new information obtained as planning proceeds. The incorporation of this information is essential to improve the content of the plan and to keep it up-to-date and useful. New information must be reviewed regularly and systematically, and the plan revised accordingly.

Public Participation

The success of the preservation planning process depends on how well it solicits and integrates the views of various groups. The planning process is directed first toward resolving conflicts in goals for historic preservation, and second toward resolving conflicts between historic preservation goals and other land-use planning goals. Public participation is intergral to this approach and includes at least the -following actions:

1. Involving historians, architectural historians, archeologists, historical architects, folklorists and persons from related discipline to define, review and revise the historic contexts, goals and priorities;

2. Involving interested individuals, organizations and communities in the planning area in identifying the kinds of historic properties that may exist and suitable protective measures;

3. Involving prospective users of the preservation plan in defining issues, goals and priorities;

4. Providing for coordination with other p!anning efforts at local, state, regional and national levels, as appropriate; and

44718 Federal Register / Voi. 48, No. 190 / Thursday, September 29, 1983 / Notices

5. Creating mechanisms for identifying and resolving conflicts about historic preservation issues.

The development of historic contexts, for example, should be based on the professional input of all disciplines involved in preservation and not be limited to a single discipline. For prehistoric archeology, for example, data from fields such as geology, geomorphology and geography may also be needed. The individuals and organizations to be involved will depend, in part, on those present or interested in the planning area.

Documents Rfesulting from the Planning

Process

In most cases, the planning process ,produces documents that explain how the process works and that discuss the historic contexts and related goals and priorities. While the process can operate in the absence of these documents, planning documents are important because they are the most effective means of communicating the process and its recommendations to others. Planning documents also record decisionsabout historic properties.

As various parts of the planning process are reviewed and revised to reflect current information, related documents must also be updated. Planning documents should be created in a form that can be easily revised. It is also recommended that the format, language and organization of any documents or other materials (visual aids, etc.) containing preservation planning information meet the needs of prospective users.

Developing Historic Contexts

General Approach

Available information about historic properties must be divided into manageable units before it can be useful for planning purposes. Major decisions about identifying, evaluating, registering and treating historic properties are most reliably made in the context of other related properties: A historic context is an organizational format that groups information about related historic properties, based on a theme, geographic limits and chronological period. A single historic context describes one or more aspects of the historic development of an area, considering history, architecture, archeology, engineering and culture; and identifies the significan't patterns that individual historic properties represent, for example, Coal Mining in Northeastern Pennsylvania between 1860 and 1930. A set of historic contexts

is a comprehensive summary of all aspects of the history of the area.

The historic context is the cornerstone of the planning process. The goal of preservation planning is to identify, evaluate, register and treat the full range of properties representing each historic context, rather than only one or two types of properties. Identification activities are organized to ensure that research and survey activities include properties representing all aspects of the historic context. Evaluation uses the. historic context as the framework within which to apply the criteria for evalution to specific properties or property types. Decisions about treatment of properties are made with the goal of treating the range of properties in the context. The use of historic contexts in organizing major preservation activities ensures that those activities result in the preservation of the wide variety of properties that represent our history, rather than only a small, biased sample of properties.

Historic contexts, as theoretical constructs, are linked to actual historic properties through the concept of property type. Property types permit the development of plans for identification, evaluation and treatment even in the absence of complete knowledge of individual properties. ike the historic context, property types are artifical constructs which may be revised as necessary.

Historic contexts can be developed at a variety of scales appropriate for local, State and regional planning. Given the probability of historic contexts overlapping in an area, it is important to coordinate the development and use of contexts at all levels. Generally, the State Historic Preservation Office possesses the most complete body of information about historic properties and, in practice, is in the best position to perform this function.

The development of historic contexts generally results in documents that describe the prehistoric processes-or patterns that define the context. Each of the contexts selected should be developed to the point of identifying important property types to be useful in ater preservation decision-making. The amount of detail included in these summaries will vary depending on the level (local, state, regional, or national) at which the contexts are developed and on their intended uses. For most planning purposes, a synopsis of the written description of the historic context is sufficient.

Creating a Historic Context

Generally, historic contexts should -not be constructed so broadly as to

include all property types under a single historic context or so narrowly as to contain only one property type per historic context. The following procedures should be followed in creating a historic context.

1. Identify the concept, time period and geographical limits for the historic context

Existing information, concepts, theories, models and descriptions should be used as the basis for defining historic contexts. Biases in primary and secondary sources should be identified and accounted for when existing information is used in defining historic contexts.

The identification and description of historic cohtexts should incorporate contributions from .all disciplines involved in historic preservation. The chronological period and geographical' area of each historic context should be defined after the conceptual basis is established. However, there may be exceptions, especially in defining prehistoric contexts where drainage systems or physiographic regions often are outlined first. The geographical boundaries for historic contexts should not be based upon contemporary political, project or other contemporary boundaries if those boundaries do not coincide with historical boundaries. For example, boundaries for prehistoric contexts will have little relationship to contemporary city, county or state boundaries.

2. Assemble the existing information about the historic context

a. Collecting information: Several kinds of information are needed to construct a preservation plan. Information about the history of the area encompassed by the historic context must be collected, including any information about historic properties that have already been identified. Existing survey or inventory entries are an important source of information about historic properties. Other sources may include literature on prehistory, history, architecture and the environment; social and environmental impact assessments; county and State land use plans; architectural and folklife studies and oral histories; ethnographic research; State historic inventories and registers; technical reports prepared for Section 106 or other assessments of historic properties; and and direct consultation with individuals and organized groups.

In addition, organizations and groups that may have important roles in defining historic contexts and values


should be identified. In most cases a range of knowlegeable professionals drawn from the preservation, planning and academic communities will be available to assist in defining contexts and in identifying sources of information. In other cases, however, development of historic contexts may occur in areas whose history or prehistory has not been extensively studied. In these situations, broad general historic contexts should be initially identified using available literature and expertise, with the expectation that the contexts will be revised and subdivided in the future as primary source research and field survey are conducted. It is also important to identify such sources of information as existing planning data, which is needed to establish goals for identification, evaluation, and treatment, and to identify factors that will affect attainment of those goals.

The same approach for obtaining information is not necessarily desirable for all historic contexts. Information should not be gathered without first considering its relative importance to the historic context, the cost and time involved, and the expertise required to obtain it. In many cases, for example, published sources may be used in writing initial definitions of historic contexts; archival research or field work may be needed for subsequent activities.

b. Assessing information: All information should be reviewed to identify bias in historic perspective, methodological approach, or area of coverage. For example, field surveys for archeological sites may have ignored historic archelolgical sites, or county land use plans may have emphasized only development goals.

3. Synthesize information The information collection and

analysis results in a written narrative of the historic context. This narrative provides a detailed synthesis of the data that have been collected and.analyzed. The narrative covers the history of the area from the chosen perspective and identifies important patterns, events, persons or cultural values. In the process of identifying the important patterns, one should consider:

a. Trends in area settlement and development, if relevant;

b. Aesthetic and artistic values embodied in architecture, construction technology or craftsmanship;

c. Research values or problems relevant.to the historic context; social and physical sciences and humanities; and cultural interests of local communities; and

d. Intangible cultural values of ethnic groups and native American peoples.

4. Define property types

A property type is a grouping of individual properties based on shared physical or associative characteristics. Property types link the ideas incorporated in the theoretical historic context with actual historic properties that illustrate those ideas. Property types defined for each historic context should be directly related to the conceptual basis of the historic context. Property types defined for the historic 'context "Coal Mining in Northeastern Pennsylvania, 1860-1930" might include coal extraction and processing complexes; railroad and canal transportation, systems; commercial districts; mine workers' housing; churches, social clubs and other community facilities reflecting the ethnic origins of workers; and residences and other properties associated with mine owners and other industrialists.

a. Identify property types: The narrative should discuss the kinds of properties expected within the geographical limits of the context and group them into those property types most useful in representing important historic trends.

Generally, property types should be defined after the historic context has been defined. Property types in common usage ("Queen Anne houses," "mill buildings," or "stratified sites") should not be adopted without first verifying their relevance to the historic contexts being used.

b. Characterize the locational patterns of property types: Generalizations about where particular types of properties are likely to be found can serve as a guide for identification and treatment. Generalizations about the distribution of archeological properties are frequently used. The

.distribution of other historic properties often can be estimated based on recognizable historical, environmental or cultural factors that determined their location. Locational patterns of property types should be based upon models that have an explicit theoretical or historical basis and can be tested in the field. The model may be the product of historical research and analysis ("Prior to widespread use of steam power, mills were located on rivers and streams able to produce water power" or "plantation houses in the Mississippi Black.Belt were located on sandy clay knolls"), or it may result from sampling techniques. Often the results of statistically valid sample surveys can be used to describe the locational patterns of a representative portion of properties

belonging to a particular property type. Other surveys can also provide a basis for suggesting locational patterns if a diversity of historic properties was recorded and a variety of environmental zones was inspected. It is likely that the identification of locational patterns will come from a combination of these sources. Expected or predicted locational patterns of property types should be developed with a provision made for their verification.

c. Characterize the current condition of property types: The expected condition of property types should be evaluated to assist in the development of identification, evaluation and. treatment strategies, and to help define physical integrity thresholds for various property types. The following should be assessed for each property type:

(1) Inherent characteristics of a property type that either contribute to or detract from its physical preservation. For example, a property type commonly constructed of fragile materials is more likely to be deteriorated than a property type constructed of durable materials; structures whose historic function or design limits the potential for alternative uses (water towers) are less likely to be reused than structures whose design allows a wider variety of other uses (commercial -buildings or warehouses).

(2) Aspects of the social and natural environment that may affect the preservation or visibility-of the property type. For example, community values placed on certain types of properties (churches, historic cemeteries) may result in their maintenance while the need to reuse valuable materials may stimulate the disappearance of properties like abandoned houses and barns.

It may be most efficient to estimate of the condition of property types based on professional knowledge of existing properties and field test these estimates using a small sample of properties representative of each type. 5. Identify information needs

F'illing gaps in information is an important element of the preservation plan designed for each historic context. Statements of the information needed should be as specific as possible, 'focusing on the information needed, the historic context and property types it applies to, and why the information is needed to perform identification, evaluation, or treatment activities.

Developing Goals for a Historic Context Developing Goals

A goal is a statement of preferred preservation activities, which is

https://relevant.to


generally stated in terms o f property types.

The purpose of establishing preservation goals is to set forth a "best case" version of how properties in the historic context should be identified, evaluated, registered and treated. Preservation goals should be oriented toward the greatest po'ssible protection of properties in the historic context and should be based on the principle that properties should be preserved in place if possible, through affirmative treatments like rehabilitation, stabilization or restoration. Generally, goals will be specific to the historic context and will often be phrased in terms of property types. Some of these goals will be related to information needs previously identified for the historic context. Collectively, the goals for a historic context should be a coherent statement of program direction covering all aspects 'of the context.

For each goal, a statement should be prepared identifying:

1. The goal, including the context and property types to which the goal applies and the geographical area in which they are located;

2. The activities required t6 achieve the goal;

3. The most appropriate methods or strategies for carrying out the activities;

4. A schedule within which the activities should be completed; and

5. The amount of effort required to accomplish the goal, as well as a way to evaluate progress toward its accomplishment.

Setting priorities for goals

Once goals have been developed they need to be ranked in importance. Ranking involves examining each goal in light of a number qf factors.

1. General social, economic, political and environmental conditions and trends affecting (positively and negatively) the identification, evaluation, registration and treatment of property types in the historic context.

Some property types in the historic context may be more directly threatened by deterioration, land development patterns, contemporary use patterns, or public perceptions of their value, and such property types should be given priority consideration.

2. Major cost or technical considerations affecting the identification, evaluation and treatment of property types in the historic context. - The identification or treatment of some property types may be technically possible but the cost prohibitive; or techniques may not currently perfected (for exAmple, the identification of submerged sites or objects, or the

evaluation of sites containing material for which dating techniques are still being developed).

3. Identification, evaluation, registration and treatment activities previously carried out for property types in the historic context. '

If a number of properties representing one aspect of a historic context have, been recorded or preserved, treatment of additional members of that property type may receive lower priority than treatment of a property type for which no examples have yet been recorded or preserved. This approach ensures that the focus of recording or preserving all elements of ths historic context is retained, rather than limiting activities to preserving properties representing only some aspects of the context.

The result of considering the goals in light of these concerns will be a list of refined goals ranked in order of priority.

Integrating Individual Con texts-Creating the Preservation Plan

When historic contexts overlap geographically, competing goals and priorities must be integrated for

-effective preservation planning. The ranking of goals for each historic context must be reconciled to ensure that recommendations for one context do not contradict those for another. This important step results in an overall set of priorities for several historic contexts and a list of the activities to be performed to achieve the ranked goals. When applied to a specific geographical area, this is the preservation plan for that area.

It is expected that in many instances historic contexts will overlap geographically. Overlapping contexts are likely to occur in two combinations-those that were defined at the same scale (i.e., textile development in Smithtown 1850-1910 and Civil War in Smithtown 1855-1870) and those defined at different scales (i.e., Civil War in Smithtown and Civil War in the Shenandoah Valley). The contexts may share the same property types, although the shared property types will probably have different levels of importance, or they may group the same properties into different property types, reflecting either a different scale of analysis or a different historical perspective.

As previously noted, many of the goals that the formulated for a historic context will focus on the property types defined for that context. Thus it is critical that the integration of goals include the explicit consideration of the potential for shared property type membership by individual properties. For example, when the same property

types are used by two contexts, reconciling the goals will require weighing the level of importance assigned to each property type. The degree to which integration of historic contexts must involve reconciling property types may be limited by the coordinated development of historic contexts used at various levels.

Integration with lVfahagement Frameworks

Preservation goals and priorities are adapted to land units through integration with other planning concerns. This integration must involve the resolution of conflicts that arise when competing resources occupy the same land base, Successful resolution of these conflicts can often be achieved through judicious combination of inventory, evaluation and treatment* activities. Since historic properties are irreplaceable, these activities should be heavily weighted to discourage the destruction of significant properties and to be compatible with the primary land use.

SECRETARY OF THE INTERIOR'S STANDARDS FOR IDENTIFICATION

Identification activities are undertaken to gather information about historic properties in an area. The scope of these activities will depend on: existing knowledge about properties; goals for survey activities developed in the planning process; and current management needs.

Standard I. Identification of Historic Properties Is Undertaken to the Degree Required To Make Decisions

Archival research and survey activities should be-designed to gather the information necessary to achieve defined preservation goals. The


objectives, chosen methods and techniques, and expected results of the identification activities are specified in a research design. These activities may include archival research and other techniques to develop historic contexts, sampling-an area to gain a broad understanding of the kinds of properties it contains, or examining every property in an area as a basis for property specific decisions. Where possible, use of quantitative methods is important because it can produce an estimate, whose reliability may be assessed, of the kinds of historic properties that may be present in the studied area. Identification activities should use a search procedure consistent with the management needs for information and the character of the area to be investigated. Careful selection of methods, techniques and level of detail is necessary so that the gathered information will provide a sound basis for making decisions.

Standard II. Results of Identification Activities are Integrated Into the Preservation Planning Process

Results of identification activities are reviewed for their effects on previous planning data. Archival research or field survey may refine the understanding of one or more historic contexts and may alter the need for additional survey or study of particular property types. Incorporation of the results of these activities into the planning process is fiecessary to ensure that the planning process is always based on the best available information.

Standard III. Identification Activities Include Explicit Procedures for Record-Keeping and Information Distribution

Information gathered in identification activities is useful in other preservation planning activities only when it is systematically gathered and recorded, and made available to those responsible for preservation planning. The results of identification activities should be reported in a format that summarizes the design and methods of the survey, provides a basis for others to review the results, and states where information on identified properties is maintained. However, sensitive information, like the location of fragile resources, must be safeguarded from general public distribution. Secretary of the Interior's Guidelines for Identification

Introduction

These Guidelines link the Standards for Identification with more specific guidance and technical information. The

Guidelines outline one approach to meet the Standards for Identification. Agencies, organizations and individuals proposing to approach identification differently may wish to review their approaches with the National Park Service.

The Guidelines are organized as follows:

Role of Identification in the Planning Process

Performing Identification Integrating Identification Results Reporting Identification Results Recommended Sources of Technical

Information

Role of Identification in the Planning Process

Identification is undertaken for the purpose of locating historic properties and is composed of a number of activities which include, but are not limited to archival research, informant interviews, field survey and analysis. Combinations of these activities may be selected and appropriate levels of effort assigned to produce a flexible series of options. Generally identification activities will have multiple objectives, reflecting complex management needs. Within a comprehensive planning process, identification is normally undertaken to acquire property-specific information needed to refine a particular historic context or to develop any new historic contexts. (See the Guidelines for Preservation Planning for discussion of information gathering to establish plans and to develop historic contexts.) The results of identification activities are then integrated into the planning process so that subsequent activities are based on the most up-to-date information. Identification activities are also undertaken in the absence of a comprehensive planning process, most frequently as part of a specific land-use or development project. Even lacking a formally developed preservation planning process, the benefits of efficent, goal-directed research may be obtained by the development of localized historic contexts, suitable in scale for the project area, as part of the background research which customarily occurs before field survey efforts.

Performing Identification

Research Design

Identification activities are essentially research activities for which a statement of objectives or research design should be prepared before work is performed. Within the framework of a comprehensive planning process, the research design provides a vehicle for' integrating the various activities performed during the identification

process and for linking those activities directly to the goals and the historic context(s) for which those goals were defined. The research design stipulates the logical integration of historic context(s) and field and laboratory methodology. Although these tasks may be performed individually, they will not contribute to the greatest extent possible in increasing information on the historic context unless they relate to the defined goals and to each other., Additionally, the research design provides a focus for the integration of interdisciplinary information. It ensures that the linkages between specialized activities are real, logical and address the defined research questions. Identification activities should be guided by the research design and the results discussed in those terms. (See Reporting Identification Results)

The research design should include the following:

1. Objectives of the identification activities. For example: to characterize the range of historic properties in a region; to identify the number of properties associated-with a context;'to gather information to determine which properties in an area are significant.

The statement of objectives should refer to current knowledge about the historic contexts or property types, based on background research or assessments of previous research. It should clearly define the physical extent of the area to be investigated and the amount and kinds of information to be gathered about properties in the area.

2. Methods to be used to obtain the information. For example: archival research or field survey. Research methods should be clearly and specifically related to research problems.

Archival. research or survey methods should be carefully explained so that others using the gathered information can understand how the information was obtained and what its possible limitations or biases are.

The methods should be compatible with the past and present environmental character of the geographical area under study and the kinds of properties most likely to be present in the area.

3. The expected results and the reasons for those expections.

Expectations about the kind, number, location,, character and condition of historic properties are generally based on a combination of background research, proposed hypotheses, and analogy to the kinds of properties known to exist in areas of similar environment or history.

44722 Federal Register / Vol. 48, No. 190 J Thursday, September 29, 1983 / Notices

Archival Research

Archival or background research is generally undertaken prior to any field survey. Where identification is undertaken as part of a comprehensive planning process, background research may have taken place as part of the developrnent of the historic contexts (see the Guidelines for Preservation Planning). In the absence of previously developed historic contexts, archival research should address specific issues and topics. It should not duplicate previous work. Sources should include, but not be limited to, historical maps, atlases, tax records, photographs, ethnographies, folklife documentation, oral histories and other studies, as well as standard historical reference works, as appropriate for the research problem. (See the Guidelines for Historical Documentation for additional discussion.)

Field Survey

The variety of field survey techniques available, in combination with the varying levels of effort that may be assigned, give great flexibility to implementing field surveys. It is important that the selection of field survey techniques and levelof effort be responsive to the management needs and preservation goals that direct the survey effort.

Survey techniques may be loosely grouped into two categories, according to their results. First are the techniques that result in the characterization of a region's historic properties. Such techniques might include "windshield" or walk-over surveys, with perhaps a limited use of sub-surface survey. For purposes of these Guidelines, this kind of survey is termed a "reconnaissance." The second category of survey techniques is those that permit the identification and description of specific historic properties in an area; this kind of survey effort is termed "intensive." the terms "rec6nnaissance" and "intensive" are sometimes defined to mean particular survey techniques, generally with regard to prehistoric sites. The use of the terms here is general and is not intended to redefine the terms as they are used elsewhere.

Reconnaissance survey might be most profitably employed when gathering data to refine a developed historic context-such as checking on the presence or absence -of expected property types, to define specific property types or to estimate the distribution of historic properties in an area. The results of regional characterization activities provide a general understanding of the historic

properties in a particular area and permit management decisions that consider the sensitivity of the area in terms of historic preservation concerns and the resulting implications for future land use planning. The data should allow the formulation of estimates of the necessity, type and cost of further identification work and the setting of priorities for the individual tasks involved. In most cases, areas surveyed in this way will require resurvey if more complete information is needed about specific properties.

A reconnaissance survey should document:

1. The kinds of properties looked for; 2. The boundaries of the area

surveyed; 3. The method of survey, including the

extent of survey coverage; 4. The kinds of historic properties

present in the surveyed area; 5. Specific properties that were

identified, and the categories of information collected; and

6. Places examined that did not contain historic properties.

Intensive survey is most useful when it is necessary to know precisely what historic properties exist in a given area or when information, sufficient for later evaluation and treatment decisions is needed on individual historic properties. Intensive survey describes the distribution of properties in an area; determines the number, location, and condition of properties; determines the types of properties actually present within the area; permits classification of individual properties; and records the physical extent of specific properties.

An intensive survey should document: 1. The kinds of properties looked for; 2. The boundaries of the area

surveyed; 3. The method of survey, including an

estimate of the extent of survey coverage;

4. A record of the precise location of all properties identified; and

5. Information on the appparance, significance, integrity and boundaries of each property sufficient to permit an evaluation of its significance.

Sampling

Reconnaissance or intensive survey methods may be employed according to a sampling procedure to examine less-than-the-total project or planning area.

Sampling can be effective when several locations are being considered for an undertaking or when it is desirable to estimate the cultural resources of an area. In many cases, especially where large land areas are involved, sampling can be done in stages. In this approach, the results of

the initial large area survey are used to structure successively smaller, more detailed surveys. This "nesting" approach is an efficient technique since it enables characterization of both large and small areas with reduced effort. As with all investigative techniques, such procedures should be designed to permit an independent assessment of results.

Various types of sample surveys can be conducted, including, but not limited to: random, stratified and systematic. Selection of sample type should be guided by the problem the survey is expected to solve, the nature of the expected properties and the nature of the area to be surveyed.

Sample surveys may provide data to estimate frequencies of properties and types of properties within a specified area at various confidence levels. Selection of confidence levels should be based upon the nature of the problem the sample survey is designed to address.

Predictive modeling is an application of basic sampling techniques that projects or extrapolates the number, classes and frequencies of properties in unsurveyed areas based on those found in surveyed areas. Predictive modeling can be an effective tool during the early stages of planning an undertaking, for targeting field survey and for other management purposes. However, the accuracy of the model must be verified; predictions should be confirmed through field testing and the model redesigned and retested if necessary.

Special survey techniques

Special survey techniques may be needed in certain situations.

Remote sensing techniques may be the most effective way to gather background environmental data, plan more detailed field investigations., discover certain classes of properties, map~sites, locate and confirm the presence of predicted sites, and define features within properties. Remote sensing techniques include aerial, subsurface and underwater techniques. Ordinarily the results of remote sensing should be verified through independent field inspection before making any evaluation or statement regarding frequencies or types of properties.

Integrating Identification Results

The results of identification efforts must be integrated into the planning process so that planning decisions are based on the best available information. The newinformantion is first assessed against the objectives of the identification effort to determine whether the gathered information meets


the defined identification goals for the historic context(s); then the goals are adjusted accordingly. In addition, the historic context narrative, the definition of property types and the planning goals for evaluation and treatment are all adjusted as necessary to accommodate the new data.

Reporting Identification Results

Reporting of the results of identification activities should begin with the statement of objectives prepared before undertaking the survey. The report should respond t6 each of the major points documenting:

1. Objectives; 2. Area researched or surveyed; 3. Research design or statement of

objectives; 4. Methods used, including the

intensity of coverage. If the methods differ from those outlined in the statement of objectives, the reasons should be explained.

5. Results: how the results met the objectives; result analysis, implications and recommedations; where the compiled information is located.

A summary of the survey results should be available for examination and distribution. Identified properties should then be evaluated for possible inclusibn in appropriate inventories.

Protection of information about archeological sites or other properties that may be threatened by dissemination of that information is necessary. These may include fragile archeological properties or properties such as religious sites, structures, or objects, whose cultural value would be compromised by public knowledge of the property's location.

Secretary of the Interior's Standards for Evaluation

Evaluation is the process of determining whether identified properties meet defined criteria of significance and therefore should be included in an inventory of historic properties determined to meet the

criteria. The criteria employed vary depending on the inventory's use in resource management.

Standard L Evaluation of the Significance of Historic Properties Uses Established Criteria

The evaluation of historic properties employs criteria to determine which properties are significant. Criteria should therefore focus on historical, architectural, archeological, engineering and cultural values, rather than on treatments. A statement of the minimum information necessary to evaluate properties against the criteria should be provided to direct information gathering activities.

Because the National Register of Historic Places is a major focus of preservation activities on the Federal, State and local levels, the National Register criteria have been widely adopted not only as required for Federal purposes, but for State and local inventories as well. The National Historic Landmark criteria and other criteria used for inclusion of properties in State historic site files are other examples of criteria with different management purposes.

Standard I1. Evaluation of Significance Applies the Criteria Within Historic Contexts

Properties are evaluated using a historic context that identifies the significant patterns that properties represent and defines expected property types against which individual properties may be compared. Within this comparative framework, the criteria for evaluation take on particular meaning with regard to individual properties.

Standard III. Evaluation Results in A List or Inventory of Significant Properties That Is Consulted In Assigning Registration and Treatment Priorities

The evaluation process and the subsequent development of an inventory of significant properties is an on-going activity. Evaluation of the significance of a property should be completed " before registration is considered and before preservation treatments are selected. The inventory entries should contain sufficient information for subsequent activities such as registration or treatment of properties, including an evaluation statement that makes clear the significance of the property within one or more historic contexts.


Standard IV. Evaluation Results Are Made Available to the Public

Evaluation is the basis of registration and treatment decisions. Information about evaluation decisions should be organized and available for use by the general public and by those who take part in decisions about registration and' treatment. Use of appropriate computer-assisted data bases should be a part of the information dissemination effort. Sensitive information, however, must be safeguarded from general public distribution.

Secretary of the Interior's Guidelines for Evaluation

Introduction

These Guidelines link the Standards for Evaluation with more specific guidance and technical information. These Guidelines describe one approach to meeting the Standards for Evaluation. Agencies, organizations, or individuals proposing to approach evaluation differently may wish to review their approach with the National Park Service.

The Guidelines are organized as follows: The Evalauation Process Criteria Application of Criteria within a Historic

Context Inventory Recommended Sources of Technical

Information

The Evaluation Process

These Guidelines describe principles for evaluating the significance of one or more historic properties with regard to a given set of criteria.

Groups of related properties should be evaluated at the same time whenever possible; for example, following completion of a theme study or community survey.

Evaluation should not be undertaken using documentation that may be out of date. Prior to proceeding with evaluation the current condition of the property should be determined and previous analyses evaluated in light of any new information.

Evaluation must be performed by persons qualified by education, training and experience in the application of the criteria. Where feasible, evaluation should be performed in consultation with other individuals experienced in applying the relevant criteria in the geographical area under consideration; for example, the State Historic Preservation Officer or local landmarks commission.

Evaluation is completed with a written determination that a property is

or is not significant based on provided information. This statement should be part of the record.

Criteria: The purposes of evaluation criteria should be made clear. For example, the criteria may be used "to evaluate properties for inclusion in the county landmarks list," or "to implement the National Register of Historic Places program."

For Federal cultural resource management purposes, criteria used to develop an inventory should be coordinated with the Natidnal Register criteria for evaluation as implemented in the approved State comprehensive historic preservation plan.

Content of Criteria: Criteria should be appropriate in scale to the purpose of the evaluation. For example, criteria designed to describe national significance should not be used as the basis for creating a county or State inventory. Criteria should be categorical and not attempt to describe in detail every property likely to qualify. Criteria should outline the disciplines or broad areas of concern (history, archeology, architectural history, engineering and culture, for ekample) included within the scope of the inventory; explain what kinds of properties, if any, are excluded and the reasons for exclusion; and define how levels of significance are mbasured, if such levels are incorporated into the criteria. If the criteria are to be used in situations where the National Register criteria are also widely used, it is valuable to include a statement explaining the relationship of the criteria used to the National Register criteria, including how the scope of the inventory differs from that defined by the National Register criteria and how the inventory could be use to identify properties that meet the National Register criteria.

Information Needed to Evaluate Properties: The criteria should be accompanied by a statement defining the minimum information necessary to evaluate properties to insure that this information is collected during identification activities intended to locate specific historic properties. Generally, at least the following will be needed:

1. Adequately developed historic contexts, including identified property types. (See the Guidelines for Preservation Planning for discussion of development of historic contexts.)

2. Sufficient information about the appearance, condition and associative values of the property to be evaluated to:

a. Classify it as to property type;

b. Compare its features or characteristics with those expected for its property type; and

c. Define the physical extent of the property and accurately locate the property.

To facilitate distinguishing between facts and analysis, the information should be divided into categories. including identification and description of pertinent historical contexts; description of the property and its significance in the historical context; and analysis of the integrity of the property relative to that needed to represent the context.

Usually documentation need not include such items as a complete title history or biography of every owner of a property, except where that information is important in evaluating its significance. Information on proposed or potential treatments or threats, such as destruction of a property through uncontrollable natural processes, is also not needed for evaluation, unless those effects are likely to occur prior to or during the evaluation, thereby altering the significant characteristic of the property. If archeological testing or structural analysis is needed for evaluation, it should not proceeded beyond the point of providing the information necessary for evaluation and should not unnecessarily affect significant features or values of the property.

When more information is needed: Evaluation cannot be conducted unless all necessary information is available. (See Information Needed to Evaluate Properties.) Any missing information or analysis should be identified (e.g. development of context or information* on the property) as well as the specific activities required to obtain the information. (archival research, field survey and testing, or laboratory testing). When adequate information is not available, it is important to record that fact so that evaluation will not be undertaken until the information can be obtained. In some cases needed information is not obtainable, for example, where historical records have been destroyed or analytical techniques have not been developed to date materials in archeological sites. If an evaluation must be completed in these cases, it is important to acknowledge what information was not obtainable and how that missing information may affect the reliability of the evaluation.

Application of the Criteria within a Historic Context

The first step in evaluation is considering how the -criteria apply to the

Federal Register / Vol. 48, No. 190 / Thursday, September 29, 1983 / Notices 1447-25

particular historic context. This is done by reviewing the previously developed narrative for the historic context and determining how the criteria would apply to properties in that context, based on the important patterns, events, persons and cultural values identified. (See the discussion of the historic context narrative in the Guidelines for Preservation Planning.) This step includes identification of which criteria each property type might meet and how integrity is to be evaluated for each property type under each criterion. Specific guidelines for evaluating the eligibility of individual properties should be established. These guidelines should outline and justify the specific physical characteristics'or data requirements that an individual property must possess to retain integrity for the particular property type; and define the process by which revisions or additions can be made to the evaluation framework.

Consideration of property type and intergrity: After considering how the criteria apply to the particular historic context, the -evaluation process ifor a property generally includes the following steps:

1. A property is classified as.to the appropriate.historic context(s) -and property type(s). If no existing.property type is appropriate, anew property type is defined, its values identified, and the specific characteristics ordata requirements are'outlined and justified as an addition to thehistoric context. If necessary, a new.historic -context is defined for which values and property types and their integrity requirements are identified and justified.

2. A comparison is made between the existing information about the property and the integrity-characteristics or data required for the property type.

a. If the comparison shows that the property possesses these characteristics, then it is evaluated as significant for that historic context. The evaluation includes a determination that the property retains integrity for its type.

b. If the comparison shows that the property does not meet the minimum requirements, one of several conclusions is reached:

(1) The property is determined not significant because it does not.retain the integrity defined for the property type.

(2) The property has characteristics that may make it significant but these differ from those expected for .that property type in that context. In this case, the historic context or property types should be reexamined and revised if necessary, based on subsequent research and survey.

The evaluation should state how the particular property meets the integrity

requirements for its type. When a property is disqualified for loss of integrity, the evaluation statement should focus on the kinds of integrity expected for the property type, those that are absent for the disqualified property, and the impact of that absence on the property's abiliiy to exemplify architectural, historical or research values within a particular historic context.

The integrity of the property in its current condition, rather than its likely condition after a proposed treatment, should be evaluated. Factors such as structural problems, deterioration, or abandonment should be considered in the evaluation only if they have affected the integrity of the significant features or characteristics of the property.

Inventory An inventory is a repository of

information-on specific properties evaluated as significant.

Content: The inventory should include:

1. Summaries of the important historic contexts. These may be in the form of an approved plan or analyses of historic contexts important in the history of the geographical area covered by the inventory.

2. Descriptions of significant property types of these contextswhether or not any specific properties have been identified.

3. Results of reconnaissance surveys or other identification activities, even if the level of information-on specific properties identified as part of those activities is iot sufficient to evaluate individual properties.

4. ilnformation on indihidual properties that was used in evaluation.

Historic contexts are identified by name, with reference to documents describing those contexts, or with a narrative statement about the context(s) where such documents do not exist.

A description of the property* Part of this description may be a photographic record.

A statement that justifies the significance of the property in relation to its context(s). This statement should include an analysis of the integrity of the property.

Boundaries of-the property. A record of when a property was

evaluated and included in the inventory, and by whom.

Records on demolished or altered properties and properties evaluated as not significant should be retained, along with full description of areas surveyed, for the planning information these records provide about impacts to properties and about the location and

character of non-significant properties to prevent redundant identification work at a later time.

Maintenance: Inventory entries should be maintained so that they accurately represent what is known about historic properties in the area covered by the inventory. This will include new information gained from research.and survey about the historic contexts, property types, and previously evaluated properties, as well as information about newly evaluated properties. For individual properties, addition of kinds of significance, change in the boundaries, or loss of significance through demolition or alteration should be recorded.

Uses andAvailability: An inventory should be managed.so that the information is accessible. Its usefulness depends on the organization of information and on its abilty to incorporate new information. An inventory should be structured so that entries can be retrieved by locality _®rby historic context.

The availability of the inventory information should be announced or a summary should be distributed. This may be in the form of a list of properties evaluated as significant or a summary of the historic contexts and the kinds of properties in the inventory. Inventories should be avilable to managers, planners, and the general.public at 'local, State, regional, and Federal agency levels.

It is .necessary to protect information about archeological sites or other properties whose integrity may be damaged by widespread knowledge of their location. It -may also be necessary to protect information on the location of properties such as religious sites, structures, or objects whose cultural value would be -compromised by public knowledge of the property's location.

Secretary of the Interior's Standards For Registration

Registration is the formal recognition of properties evaluated as significant. Preservation benefits provided by various registration programs range from honorific recognition to prohibition of demolition or alteration of included properties. Some registration programs provide recognition and other broad benefits while other programs authorize more specific forms of protection.

Standard . Registration Is Conducted According To Stated Procedures

Registration of historic properties in the National Register of Historic Places must be done in accordance with the National Register regulations published in the Code of Federal Regulations, 36 CFR 60. Registration for other lists or purposes follow an established process that is understood by the public, particularly by those interests that may be affected by registration.

Standard I1. Registration Information Locates, Describes andJustifies the Significance and Physical Integrity of a Historic Property

Registers are used for planning, research and treatment. They must contain adequate information for users to locate a property and understand its significance. Additional information

may be appropriate depending on the intended use of the register.

Standard III. Registration Information is Accessible to the Public

Information should be readily available to the public and to government agencies responsible for the preservation of historic properties and for other planning needs.

Secretary of the Interior's Guidelines for Registration

Introduction

These Guidelines link the Standards for Registration with more-specific guidance and technical information. They describe one approach to meeting the Standards for Registration. Agencies: organizations, or individuals proposing to approach registration differently may wish to review their approach with the National Park Service.

The Guidelines are organized as follows: Purpose of Registration Programs Registration Procedures Documentation on Registered Properties Public Availability Recommended Sources of Technical

Information

Purpose of Registration Programs

Registration of historic properties is the formal recognition of properties that have been evaluated as significant according to written criteria. Registration results in an official inventory or list that serves an administrative function. A variety of benefits or forms of protection accure to a registered property, ranging from honorific recognition to prohibition of demolition or alteration.

Some registration programs provide recognition and other broad benefits or entitlements, while other registrations of properties may, in addition, authorize more specific forms of protection. The application of the registration process should be a logical outgrowth of the same planning goals and priorities that guided the identification and evaluation activities. All registration programs should establish priorities for rec6gnition of their authorized range of properties: provide for confidentiality of sensitive information: and establish a means of appealing the registration or non-registration of a property.

Registration Procedures

Explicit procedures are essential because they are the means by which the public can understand and participate in the registration process. Procedures for registration programs should be developed by professionals in

the field of historic preservation, in consultation with those who will use or be affected by the program. Prior to taking effect, procedures should be published or circulated for comment at the governmental level at which they will be used. (Procedures for registration of properties in the National Register of. Historic Places and the National Historic Landmarks list, for expmple, are published in the Federal Register.)

Any registration program should include:

1. A professional staff to prepare or assess the documentation;

2. A professional review, independent of the nominating source, to provide an impartial evaluation of the documented significance;

3. Adequate notice to property owners, elected officials and the public about proposed registrations and the effects of listing, ifany; and

4. A means of public participation. Professional Review: The registration

process should include an independent evaluation of the significance of the property and of the quality and thoroughness of the documentation supporting that significance. Such evaluation ensures that significance is adequately justified and that registration documentation meets the technical requirements of the registration process.

State and local preservation programs, concerned with both public and private properties, generally use a review board, panel or commission. This level of professional review has proven to be effective in assessing the significance of properties considered for registration.

Review boards and other forms of independent review should include professionals in the fields or diciplines included in the criteria; representatives of other fields or disciplines may be desirable to reflect other values or aspects of the register. Key personnel must be qualified by education, training or experience to accomplish their designated duties. (See the Professional Qualifications Standards.)

The scope of the independent review should be clearly stated in the registration procedures and should not include issues outside the scope of the applicable criteria for evaluation and other areas specified in the procedures. Generally, independent reviewers should not be involved in any primary research or analysis related to properties under consideration; this information should be gathered and organized prior to review meetings. Documentation presented to the reviewers should be made available to


the public prior to review meetings or public hearings. Registration of properties should not take place until review of documentation has been completed.

Public Notice: Adequate notice allows property owners, officials and other interested parties to comment on proposed registrations prior to action by the independent reviewers. The degree of protection and control provided b-y a registration program may be a factor in determining what constitutes adequate notice. For example, adequate notice of proposed inclusion.in honorific registers may be less complex than that for registration that results in local controls on alteration or demolition of registered properties.

Notice to elected officials and the public is necessary to distribute information about potential registrations of concern to planning and development interests.

Adequate notice to property owners may be accomplished through means ranging from individual notification by mail to publication of a public notice, depending on the nature of the registration program and the number and character of the properties involved.

Public notices and owner notification about proposed registrations should include the dates and times of public meetings and review meetings, the kinds of comments that are appropriate, and how comments will be considered in the evaluation process. The notice should also state where information can be obtained about the registration program, the criteria used to evaluate properties for inclusion, and the significance of specific properties under consideration.

The procedures should include a means of public participation in the form of submission of written comments or a review meeting open to the public or a public hearing.

The procedures should state time periods within which reviews, notices, comments, public hearings, review meetings'and appeals will occur. The time periods should be short enough to allow for efficient recognition of historic properties but also allow adequate time for public comment and participation by those affected. Time periods may vary depending on whether activities are carried out at the local, State, or national level. These time schedules should be widely circulated so that the process is widely understood.

Appeal Process: A means of appeal should be included in the registration process to allow for reconsideration of a property's inclusion. Reasons for appeal may range from existence of additional information about the property supporting or refuting its significance to

administrative or procedural error. An appeal process should specify to whom an appeal may be made and how the information that is provided will be evaluated. The appeal procedures should also state the time limit, if any, on appealing a decision and on consideration of information and issuance of a decision by the appeal authority.

* Documentation on Regstered Properties

Documentation requirements should be carefully weighed to provide the information actually needed to reach a registration decision and should be made public. It should be made certain that identification and evaluation activities obtain and record the information necessary for registration. Documentation should be prepared in a standardized format and on materials that are archivall stable and easy to store and retrieve.

Location: The precise location of a historic property must be clearly identified.

Street address, town or vicinity, and county should be provided. Properties should also be located on maps; these may be USGS maps, county planning maps, or city base maps or real estate maps. A uniform system of noting location, such as UTM grid points or longitude and latitude, should supplement mapping. It is recommended that each registration process standardize the preferred choice of maps appropriate to the scope of the process.

Description: An accurate description of a property includes a description of both the current and historical physical appearance and condition of the property and notes the relevant property type(s) for the applicable historic context(s). Discussion should include alterations, deterioration, relocation and

-other changes to the property since its period of significance.

Significance: A statement of significance should explain-why a property meets the criteria for inclusion in the register to which it has been nominated.

This statement should contain at least 3 elements:

1. Reference to the relevant historic context(s);

2. Identification of relevant property types within the context and their characteristics; and

3. Justification that the property under. consideration has the characteristics required to qualify it.

Relevant historic contexts can be identified through reference to the preservation plan or other documents where the contexts have been

previously described or can be provided by a narrative discussion of the context. (The development of contexts and their use in evaluating properties are discussed in the Guidelines for Preservation Planning and the Guidelines for Evaluation.) A significant property type and its characteristics are identified either through reference to the historic context(s) or by a narrative in the documentation that describes historic contexts. Justification of a specific property is made by systematic comparison of its characteristics to those required for the property type.

Boundaries: The delineation and justification of boundaries for a registered property are important for future treatment activities. It is expecially critical when legal restraints or restrictions may result from the registration of properties. Thus, boundaries should correspond as closely as possible to the actual extent and configuration of the property and should be carefully selected to encompass, but not exceed, the extent of the significant resource(s). The selection of boundaries should reflect the significant aspects of the property.

Arbitrary boundaries should not be chosen for ease of description since this can result in the inclusion of unrelated land or in exclusion of a portion of the historic property. Present property lines should not be chosen as property boundaries without careful analysis of whether they are appropriate to the historic property. A single uniform boundary description and acreage should not be applied to a group or class of properties (antebellum plantations, for example) without examination of the actual extent of each property. The selected boundaries should be justified as appropriate to the historic property.

Boundaries should be clearly and precisely described, using a verbal boundary description, legal description, accurate sketch map, or lines drawn on base maps, or a combination of these where needed to specify the limits of the property being registered. When used, maps should show the location of buildings, structures, sites or objects within the boundary.

Updating Information on Registered Properties: A change in the condition of the significant features of a property may require a change in the official registration record. Alteration of a significant architectural feature, for example, could mean that a property is no longer significant for its architectural design.

Additional significance of registered properties may be identified through development of new historic contexts.

https://inclusion.in


Research may reveal that a property is significant in other historic contexts or is significant at a higher level. For example, a property previously recognized~as of local significance could be found to be of national significance.

A change in location or condition of a registered property may mean that the property is no longer significant for the reasons for which it
